Impact ionization and avalanche multiplication of electrons and holes in the presence of a large electric field. The excess energy is given off to generate an electron-hole pair through a band-to-band transition. This generation process causes avalanche multiplication in semiconductor diodes under high reverse bias : As one carrier accelerates in the electric field it gains energy. The kinetic energy is given off to an electron in the valence band, thereby creating an electron-hole pair. The resulting two electrons can create two more electrons which generate four more causing an avalanche multiplication effect. Electrons as well as holes contribute to avalanche multiplication.  1, record 1, English, - avalanche%20multiplication%20effect

If a monochromatic primary beam of electrons is incident on a solid surface, the majority of incident electrons lose their energy because they interact strongly with matter, leading to plasmon excitation, electron-hole pair formation, and vibrational excitation.  3, record 2, English, - inelastic%20mean%20free%20path

Le domaine spectral exploré en analyse Auger […] Il convient […] de distinguer entre la longueur d’atténuation […], qui est une grandeur empirique facile à utiliser en pratique mais qui repose sur l’hypothèse d’une atténuation exponentielle, et le libre parcours moyen inélastique (IMFP : inelastic mean free path) qui est une grandeur physique calculable à partir des interactions inélastiques d’électrons lents se propageant en zigzag dans le matériau considéré.  1, record 2, French, - libre%20parcours%20moyen%20in%C3%A9lastique
